【摘要】：随着物联网技术的日益发展和人们对食品质量安全问题的不断重视,国家各级政府和企业搭建了大量的针对各类商品的信息溯源系统。然而由于这些溯源系统所采用的物品标识标准、信息服务接口等互不兼容,因此往往只能成为局部范围内的闭环应用,难以实现开环物联网集成和供应链信息实时共享。本文在充分调研了物联网物品解析服务和信息发现服务的国内外研究现状的基础上,基于EPCGlobal国际组织提出的物联网信息服务框架,结合国内物联网开环应用的实际需求,设计了一种能够支持异构物品解析和海量数据下单品粒度信息发现的物联网寻址系统。本文设计了一种能够动态支持异构物品编码解析的ONS服务机制。通过设计了一种将编码解析规则形式化的方法,使编码解析规则从解析程序中解耦,并引入OID对异构编码的类别进行管理,设计了与之对应的ONS系统架构,使扩展后的物品标识解析服务能够可扩展性地动态支持多种异构编码的解析。本文设计了一种对物联网物品标识及其解析服务提供安全保护的机制。具体为利用植入基于密钥的安全扩展码的方式将编码进行扩展,使伪造、篡改或输错的物品标识能够被有效识别。同时使用DNSSEC技术对物品解析服务进行保护,使其免受“缓存投毒”等攻击,从而保证用户将会被定向至安全可信的信息源。本文设计了一种基于Key-Value存储模式的轻量索引式信息发现服务,并利用HBase技术,大大提升了信息发现服务器对大并发量的信息发现请求响应能力和信息发布请求的响应能力,为海量数据的开环物联网下的单品粒度信息发现提供了一种可行方案。
[Abstract]:With the development of Internet of things technology and the importance of food quality and safety, governments and enterprises at all levels have set up a large number of information traceability systems for all kinds of commodities. However, these traceability systems are not compatible with each other in terms of object identification standards and information service interfaces, so it is difficult to implement open-loop IOT integration and real-time information sharing in supply chain because it is only a closed loop application in local scope. Based on the domestic and international research status of Internet of things (IoT) analysis services and information discovery services, based on the Internet of things information service framework proposed by the EPCGlobal international organization, combined with the domestic Internet of things open loop application of the actual needs, This paper designs an Internet of things addressing system which can support heterogeneous item parsing and single product granularity information discovery under massive data. In this paper, we design a ONS service mechanism that can dynamically support heterogeneous item coding and parsing. In this paper, a method of formalizing the encoding parsing rules is designed to decouple the encoding parsing rules from the parser, and OID is introduced to manage the classes of heterogeneous coding, and the corresponding ONS system architecture is designed. The extended article identification resolution service can scalable and dynamically support the resolution of multiple heterogeneous codes. In this paper, we design a mechanism to provide security protection for Internet of things (IoT) logos and their parsing services. In this paper, the security extension code based on the key is embedded to extend the code, so that the forged, tampered or incorrectly marked objects can be effectively identified. At the same time, DNSSEC technology is used to protect the item parsing service from "cache poisoning" and other attacks, so as to ensure that the user will be directed to a secure and trusted information source. In this paper, a lightweight indexing information discovery service based on Key-Value storage mode is designed, and the response ability of information discovery server to large concurrent information discovery requests and information publishing requests is greatly enhanced by using HBase technology. It provides a feasible scheme for the discovery of granularity information of individual product under the open loop Internet of things for massive data.
